Not long ago, one of the nation’s most dreaded diseases was polio, paralyzing and sometimes killing its victims. Fortunately, polio proved no match for medicine. Just as polio reached its peak in 1952 with 57,000 new cases, a University of Pittsburgh team, led by Dr. Jonas Salk, was testing a…
We brush to stave off cavities and bad breath. But it may even help us avoid major diseases. Research shows that the plaque build-up in our mouths may contribute to plaque build-up in our brains and heart arteries.

Science and technology march along, year after year, making gradual progress in transforming our lives. Every now and again, however, a public event is staged — the moon landing, a computer playing a chess champion, decoding the human genome — that gives the public the appearance of a breakthrough.
The year is 2020. You’re driving home from work, listening to your favorite satellite radio station. An announcer interrupts with breaking news: Smallpox has broken out in Washington, D.C. Hundreds of patients are flooding hospitals, with untold more infected. The public is panicked. Local officials are scrambling to maintain control.
It’s a crisp November morning, some 25 years ago. Bob Ging and Don Gales are hunting on a ridge in Lower Turkeyfoot, Somerset County, where green hemlocks mingle with bare winter hardwoods. “Boy, this is beautiful,” says Ging as sunrise reveals the emerald waters of Laurel Hill Creek in the…
